ABSTRACT:
A Metal Detector with windings placed so as to originate multipolar electromagnetic fields, including two or more pairs of transmitter Tx and Receiver Rx windings, in which the different pairs are characterized by having a different number of poles so that the simultaneous passage of two or more metal masses on parallel trajectories will never cause equal and opposite inducted signals in the Rx windings, with a zero resultant so that such masses are detected in any case.
